CONCRETE-WOOD COMBINATION RAILROAD-TIE.

Application filed September 27, 1915.

To all'whom it may concern: I

Be 1t known that I, EDWIN Rooms, a

citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented a certain new and useful Improvement in Concrete-Wood Combination Railroad-Ties, of which the following is a specification.

This invention relates to railroad tracks.

The object of the invention is to provide av device, particularly when concrete ties are used, in which the rails may be readily made to conform to the wheels of the passing train, this particularly in the case where Y there is a slight difference in the gage of the track at different points, and more particularly to provide means for accommodating the normal up and down movement of the portion of the rail which takesplace as a. heavy train passes over the track without pulling the ties more or less out of the road bed as happens more or less in ordinary prpctice, particularly where the road bed is so t.

A further object of the invention is to provide a device of this class which can be very economically constructed and readily installed, which is satisfactory in operation and not readily liable to get outof order.

The invention consists in a device capable of carrying out the foregoing objects and one having the special features and details which will be hereafter more fully descridlloed and claimed as the specification procee s.

Referring to the drawings, in which similar numerals represent the same parts throughout the several views, Figure 1 is a plan view of a piece of track constructed in accordance with this invention. Fig. 2 is a vertical sectional detail view taken transversely of the tie and parallel to the rail on the line 2-2 of Fig. 3. Fig. 3 is a cor responding view at right angles to that of Fig. 2, taken on the line 3-3 of Fig. 2. Fig. 1 is a plan view taken near the top of the tie on the line 44 of Fig. 3.

I prefer to use concrete ties and in the drawings the numeral indicates the concrete body of this tie. On the under side is placed a wooden member 12 having between it and the concrete portion of the tie, a filler 14 of burlap soaked in tar, tar paper, or the like.

On the top of the concrete portion 10 of the tie are placed two wooden boards 16 Specification of Letters Patent.

and 18 separated from each other by a filler 21 very much like the filler 14, heretofore described. Through the members'thus far described a series of bolts 22 are passed at points outside the lines of the rails 24:. These rails 2 1 are secured to wooden members 16l8 by bolts 26 having flanges 28 grasping the rail flange just as an ordinary rail spike does, the nuts 30 on these bolts 26 being placed in suitable recesses 32 formed in the top of the concrete portion 10 of the tie. These nuts 30 are ofnon-circular form and the recesses 32 are also non-circular so that when the nuts are in place in the recesses, as shown in Fig. 4, they are locked against rotation, and consequently the bolts 26 cannot become loose.

The bolts 22 are wrapped with tarred adjacent bolt 22 thereby allowing the rail to aline itself as a train passes, if it was not accurately placed in alinement in the original adjustment; and also the rail can move up and down slightly, using the portion of the members 18 and 16 between the rail and its adjacent bolt 22 as a spring, thus enabling the rail to move vertically to accommodate the passing load without pulling the heavy solid portion 10 of the tie out of the bed of the track. This is a great advantage over the practice heretofore of allowing not only the rail but the ties to move vertically in the road bed.

The use of the filler 21 between the members 16 and 18 is of a special advantage in that it allows more spring action to these members as described in the last paragraph in winter time when the wood is permeated with moisture and frozen, the idea being that the filler 21 does not take moisture and does not freeze, whereas if the members 16-18 were made solid the moisture in these parts would become practically one solid cake of ice and thereby greatly prevent the spring of the combined members 16-18 in the manner described. This filler also, of course, serves, because of the tar contained in it, as more or less of a preservative of the wooden members 16 and 18.

The recess 32 is preferably filled with tar or asphalt 10 put in place as the parts are assembled which serves to fill in all waste spaces andmake the combined structure a solid one from which moisture and the like are excluded.

Having thus described my invention, What I claim as new and desireto secure by Letters Patent, is

1. A railroad tie-comprising a body of concrete, a Wooden member secured along the lower surface of the concrete tie, another Wooden member secured along the upper surface of the tie, bolts passing through the members heretofore enumerated to hold them'together, and-means for securing a railroad rail to the upper Wooden member on the tie without securing it directly to the tie-body.

2. In, a device of the class described, a railroad tie made of concrete having on its bottom a Wooden plate, a layer; of asphaltum between said Wooden plate and the bottom of the tie, a Wooden member on the top of the tie, a layer of tar on top of said last mentioned Wooden member, another wooden member on top of the last mentioned layer of tar, means for securing all of the parts heretofore enumerated together, and means for securing a railroad rail to the tie.'

S. In a device of the class described, a tie having a concretebody member, Wooden members above and below the same,-bolts securing thepart's enumerated together, the bolts being wrapped with tarred thread or 'cord and means for securing a railroad rail to the top Wooden member.

In W tness whereof, I have hereunto subscrlbed my name in the presence of tWo Witnesses.
